Scientists that study the effects of global warming predict that a change in Earth's average temperature of even a few degrees will have dramatic effects. One consequence of global warming is the melting of the polar ice caps, which will in turn affect polar bears that use sea ice as a platform for hunting seals. What will most likely happen to the population of polar bears as a result of global warming?

It will decrease as the habitat for polar bears decrease.

It will increase as the polar bears adapt to other habitats.

It will increase because polar bears will have few predators.

It will decrease because polar bears will become easier to hunt.
